3. Review old action items
- Adam proposed we cover the following at the next meeting:
- Establish consensus on goals and constraints
- What are we trying to achieve?
- What restrictions are we faced with?
- All: do we feel SJTAG is requiring a new test language to obtain the information needed for diagnostics or is STAPL/SVF sufficient? see also Gunnar's presentation, in particular the new information he'd be looking for in a test language
(http://files.sjtag.org/Ericsson-Nov2006/STAPL-Ideas.pdf) - Ian/Brad: Condense gateway comments and queries into a concise set of questions. - Ongoing
- All: Forward text file to Ian containing keywords from review of meeting minutes. - Ongoing.
- Carl/Brad: Get annotated keyword worksheets to Ian by Wednesday Close of Business. - Ongoing
- All: Consider how a keyword can be used to define the chain configuration for a given test step, and what that keyword might be.
- Harrison: Prepare slide showing matrix of industry sectors by volume/mix. - Ongoing.
4. Discussion Topics
- Languages and descriptions
- Refer to 2009 survey Q3.5-Q3.8
(http://www.sjtag.org/survey2009/survey2.html)- In Q3.5 which do we think is related to structure and which to control/behaviour?
- Eric: System Verilog?
- Heiko: VHDL, NSDL, HSDL (part of 1149.7, but maybe just for scan chain?)
- Tim: I believe HSDL also for merging net lists
- Eric: merging net lists would become important for us, wouldn't it?
- Eric: STAPL got quite a few nods, would that be suitable for SJTAG;
- Heiko: yes, in the early days of SJTAG STAPL (and extensions to it) has been discussed quite a bit (see also our document archive on the SJTAG website)
- How might these relate to ICL, PDL?
- Tim: I think any higher language language we are choosing would need to be able to be integrated with the target system would be working with
(e.g. for turning on/off power, controlling system functions, etc.);
- Do the subjects in Q3.7 and Q3.8 describe more than structure?
- Heiko: at least a few of those language should be able to describe behavior/control as well (VHDL, Verilog, for example)
- Tim: many tools can export to VHDL; tools then should be able to merge VHDL files for board level (e.g. Menor DxDesigner)
- Tim: board level VHDL would describe the in's and out's of the board; system VHDL could then merge those board interfaces;
- Tim: problem might be various possible configurations; would need some tool that can handle the dynamic possibilities of system hardware configurations;
- Heiko: interesting idea; that would also allow people to hide details about the system
- Harrison's industry sector matrix (if available)
- not present
5. Key Takeaway for today's meeting
- languages listed in Q3.5a through Q3.5i don't define structure of a system
